About this app

The speed of strikes is the most important quality in martial arts, the strength of impact depends on the speed. This application gives the most accurate information, based on scientific data, on the speed and strength of your impact. You can compare your results with the results of athletes from around the world. The app gives an estimate of the impact strength and energy costs. Shows the progress of your workouts. With this application you can increase the effectiveness of your workouts - train and check your progress in speed and response!
Now you can:
- Check your speed during a fight with the shadow during the round;
- measure the impact force and energy costs;
- compare their results in online mode with athletes from around the world;
- to see the progress of your high-speed qualities for different periods of time: for a day, a week, a month.

To perform a test to measure the speed of impact and reaction, you must:
1. Take the phone vertically in your hand.
2. Select the round time.
3. Press the "Start" button.
4. On a sound signal, as soon as possible, to strike. The kick can be any: straight, lateral, uppercut. Strike blows until the end of the round signal sounds.
4. As a result of the test, you will learn:
- acceleration of your impact;
- speed of your impact;
- the time of a simple motor reaction;
- impact force (approximately);
- energy costs.

A simple motor reaction is a response in advance known movement to a previously known (suddenly appearing) signal (auditory, visual, tactile). In this case, an audio signal is used.
The test start signal sounds at random intervals, which complicates the test and makes it more reliable

Success in your martial art!

Thist is a powerful app that should really improve your punching speed, power and reaction times! You set the length of time for workout "round". There will be a bleep approximately once every four seconds. You hold your phone in your hand and punch as fast and hard as you can as soon as you hear each bleep. The app records how fast and powerfully you punched, as well as how soon after the bleeps you reacted, and keeps track of your progress. I was however hoping for a more simple app that just counts how many punches (perhaps above a certain speed/acceleration) that I do in a round. It might ideally allow me to set a target, and bleep at that rate. All that would really be needed is the ability to set the number of bleeps, making them regular rather than random. You could call this second mode "Speedbag." And maybe this app almost does this already because in the progress report I think it did count how many punches I did. If this were displayed at the end of the round in the round report then maybe that would be enough.

Lol we all know the speeds is not legitimate speeds. You wouldnt get that type of accuracy from a phone app, the numbers are all for fun but it gives you a goal to work with for yourself. Technically for me my hooks thru the app accelerates over 235 mph and overall speed is 129mph and 142mph max numbers respectfully. So guessy new goal is to break those numbers ad set new personal highs.

What's new

Fixed a number of bugs. The algorithm for calculating the acceleration, speed and force of impact is improved.
